(5) introducing high-pressure ammonia gas into a gas storage tank, and allowing the ammonia gas in the gas storage tank to enter an impeller through a constant pressure valve after reaching a rated pressure to drive a generator to generate electricity;
(6) introducing the low-temperature low-pressure ammonia gas after power generation into the cold dissipating device of the refrigeration house by using a second fan, simultaneously introducing the rest low-temperature low-pressure ammonia gas into a heat exchanger, reducing the temperature of the refrigeration house by absorbing heat in the atmosphere of the refrigeration house by the low-temperature low-pressure ammonia gas entering the cold dissipating device of the refrigeration house, and absorbing the heat in the atmosphere by the ammonia gas entering the heat exchanger through the heat exchanger;
(7) introducing the ammonia gas after absorbing heat in the cold radiator of the refrigeration house into a second absorption tower to form ammonia water, and introducing the ammonia gas in the heat exchanger into a first absorption tower to form ammonia water;
(8) and introducing the ammonia water in the first absorption tower and the ammonia water in the second absorption tower into a liquid storage tank for storage.
